14.2 List of parameters
Dependency: See also: p9601
See also: F01690
Note
The checksum changes when configuring safety functions.
r9782[0...1] SI change control time stamp
Data type: FloatingPoint32
Description: Displays the time stamps for the checksums for tracking changes for safety functions.
Each new checksum is assigned a time stamp (r9781).
Index: [0] = SI time stamp for checksum to track functional changes
[1] = SI time stamp for checksum to track hardware-specific changes
Dependency: See also: p9601

r9790[0...1] SI Motion SLA acceleration resolution
Data type: FloatingPoint32
Description: Displays the acceleration resolution (load side) for the "SLA" function.
Setpoints for acceleration limits or parameter changes for acceleration levels below this threshold have no effect.
Index: [0] = Coarse resolution
[1] = Fine resolution
Note
This parameter does not provide any information about the actual accuracy of the acceleration sensing. This depends
on the type of actual value sensing, the gear factors as well as the quality of the encoder being used.
Conversion of:
(internal fixed value/ Tsi²) to m/s² (linear) or 1/s² (rotary) with Tsi = p9500 (SI motion monitoring clock cycle)
Example:
For Tsi = 12 ms, r9790[0] = 0.006944 m/s² (linear) or 0.019290 1/s² (rotary) is obtained.
For Tsi = 12 ms, r9790[1] = 0.000006944 m/s² (linear) or 0.000019290 1/s² (rotary) is obtained.
Internal calculation, which also incorporates the factor for the motor-load side conversion, the gearbox ratio and the
safety monitoring clock cycle.
Result for a coarse resolution is 0.006944 m/s² (linear) - or 0.019290 1/s² (rotary).
Result for a fine resolution is 0.000006944 m/s² (linear) - or 0.000019290 1/s² (rotary).
The result listed above is applicable for the default setting of spindle pitch and gear unit stage.
SLA: Safely-Limited Acceleration
r9795 SI diagnostics F01611
Data type: Unsigned32
Description: Displays the number of the cross-checked data, which resulted in fault F01611.
Dependency: See also: F01611
Note
A complete list of numbers for cross-checked data items appears in fault F01611.
